Geochemical Evidences of Paleoenvironmental Changes in Late Quaternary Lacustrine Sediments of the Konya Closed Basin (Konya, Turkey)

Important geochemical evidence reflecting Quaternary climatic changes was obtained by evaluating geochemical data from 51 samples and datings from 3 samples by ESR method from sediments of a 7-m-deep trench in Great Konya lake area at the southwest of Adakale village (Konya, Turkey). The geochemical data indicate that the study area was influenced, four times, by a climate having strong precipitation, which caused strong erosion and high detrital input between 25,276 ± 1732-year BP and approximately 50,000-year BP. These periods correspond to climatic changes during the last glacial periods, the warm climate of D-O-2, D-O-5, D-O-6 and D-O-14 events and the cold climate of H2, H3, H4 or H5 and H6 events.
